Rectifier Management
obj,attr description
gm1,fsp
Rectifier float set-point
gm1,bsp
Rectifier boost set-point
gm1,rme Redundancy monitor enable
Rectifier Float Set-point: The voltage at which the plant will float charge the battery strings.
Rectifier Boost Set-point: The voltage at which the plant will boost charge the battery strings.
Redundancy Monitor Enable: Activates the Redundancy Loss alarm feature.
Rectifiers
obj,attr description
gsr,stt Individual rectifier state
gsr,adc Individual rectifier current
Individual Rectifier State: When requested, shows the state of the individual rectifiers. Note that the
rectifier numbering starts from the left-most position of the master shelf (shelf number 1.)
When obtaining individual rectifier status information, the following information may be transmitted:
ON: Rectifier operating normally. User may use ope to turn ON a rectifier in standby.
•
OFF: Rectifier has been shutdown due to hardware failure.
•
STANDBY: User has inhibited the rectifier's output voltage. User may use ope to place a rectifier into a standby
•
condition.
MISSING: An acknowledged rectifier has been removed.
•
VACANT: Rectifier has not been installed in that position.
•
Rectifiers may also be put in standby; however, the ability to place rectifiers in standby requires some
backup plan to take the rectifier out of standby automatically under a low voltage condition. The
battery on discharge (BOD) threshold is used as a rectifier-on voltage threshold. In other words, when
the plant voltage dips below the BOD threshold, the controller turns on all rectifiers that are in standby.
Individual Rectifier Current: When requested, shows the current output from an individual rectifier.
